Improvement in corn-planters



UNITED STATES PATENT FEICEt IMPROVEMENT IN CORN-PLA-NTEFGS.l

Specint-uiion forming part 'of Let-ters Patent No. 29,0416, dated qJuly'ltlflbt).

To all trimm it may concern:

' Be it known that. I, SAMUEL AVERY, ot Pisgah, in the county otl Cooper and State ot' Missouri, have invented a new and Improved Gorn- Planter; and l do hereby declare thatthe following is a full, clear, and exact description ot' the same, reference being had to the accompanying drawings, making a part ot' this speci-- well be moved across a large field twice in suc` cession in two places, owing to the nnevenness.

of the ground, and for this reason those machilies whose spacing-ott or check-rowing de- `\vices are connected with thc driving-wheels cannot work perfectly unless somtl means be provided whereby the driver can regulate the machine Whileit is in motion. 'lo obviatc theseV ditticulties my invention consists in a peculiar arrangement of gear-wheels operated by means of driving-wheels which support the machine, an d connected with a -shat't that transmits motion Ato the various parts of the machine. 'lhese gear-wheels serve to regulate the two driving-wheels, so that each shall make exactly the same number ot revolutions in a given time, thus obviating side dratt, which is likely to occur when obstructions come in the way ot thc wheels, and they are so arranged that they can be thrown into and out of gear at the pleasure of' the operator and it consists in the application of brakes to the drivingwheels in such a manner as to control their revolutions when passing over uneven ground,v

is mounted on two wheels, B B. These wheels .B B are fitted' loosely oli-axles projecting from each end of the frame A. n 0n the inner end ot" the hub ol' each wheel B there is secured acog-wheel, b, which gears with a smaller wheel, b', on the end ot' the shaft D, said gearing giving a rotary motion to this shaft D.

Near each end of the shaft D a cam, c, is secured, which, in the motion-of the shaft D, strikes against a projectiomyd, on the bar E, giving to said bar`a longitudinal thrust. The bar E is providedwith a spiralspring, c, which is coiled around it in such a manner that it causes the bar to tly back to its original position after beingacted uponby thecam c. Each end of this bar ll is provided with a seed-slide, which works under the hoppers, so as to regulate the discharge of seed. l

. F F F are three hoppers having their bottoms perforated with sced-cellsf. These'hoppers are mounted on thc longitudinal beams ot" the fratrie A, iust behind the main-shaft I). To the under side of each hopper F there is secured a. tube, g, for conducting the kernels to the ground, and near thelower cud ot' each tube there is a valve, h, operated by means ol' to the har E. This valve serves to contain the quantity ot' one discharge until' itis opened by means of the cam c striking against the projection on the bar 1C, when thc kernels drop to the ground without being scattered, which would not be the. case it' they t'ell direct from thehoppers.

G G are two lime-boxes mounted on thc back part ot the frame A, and having perforations in their bottoms. there is placed a ratchet-wheel, H, having-eight -the end ot" a slide-bar, 'I,. said bar being operated by means ot levers It', upon which the cams c act. Each ratchet-wheel II' hasahole made through it, which hole at every eighth A represents theframeof the machine, which a metal strip, t', one' end ot' which is secured Under cach box (l teeth, and operated by means ot` a'pa\vl-,j, on`

lowing a-jet of lime or other white substance, to pass downl through the tube muto the ground.

The lime thus deposited serves asguidemarks to enable the driver to regulate his machine so that it shall discharge the corn at the proper time tomake the rows even and equidistant from each other. Thebarl isalso provided with a spiral spring,re, which causes it to bethrown back after the operation Lof the cam c on the lever k; and itis' also provided with a hand-rod,-J, which projects up just behind the drivers seat' K,'sothat by taking hold ot' it with his hand he can adjust the ratchet-wheel,`

after turning the. machine, so that its registering with the hole in the bottom of the limebox shall-exactly correspond to deposits of lime already made..

L L L are the shoes; for making the drills in which the corn is lto be planted. These shoes are placed directly in front of tbe seed-tubes g, and vthey are attached tothe lower ends ot' rods that are hinged to the forward part of frame A. They are thus capable of a free upward and' downward motion, and will conform to any unevenness of ground.

To the shoes L, and just behind the tubes g, are attached the coverin g-rollers M, which serve to press the earth over the deposited corn.

N i-s a-haud-lever, which serves tooperate a bar, 0, passing transversely under the frame, and'bent so aste pass up through slotsm'ade in the side longitudinal beams of the frame A.' 0n theends of thiabar, and on the side beams, slides I are fitted, which are operated by the` hand-lever N in such a manner as to throwlthe cog-wheels b and b into and out of gear,y so that the -machine may be readily turned, after having vmade its transit across the ield,'witl1out deranging the other parts. A spring-bar, n, edge, (see Fig. 1,) serves to holdL-the lever N in the desired position. v

. The wheelsB B are .provided with 'brakes P','whichj\are `operated by means of a footlever, p.' These brakes serve to enable the driverlto regulate-the motion of the driving.

wheels Bnwhenpassing yover the. ground.

The operatiozrV isas follows: As the machine l is drawn along, the wheels B B give motion to the` .gearing b b', 'and consequently a rotary having notches out in itsV motion to the shaft D. The cams c on the said shaft strike onceduring everymevolution against the projections dbnthe bar E, causing the perforations in the plates on the ends of said bar E to register with the holes in the bottoms of the hoppers F, andv thereby permitting the charges of seed to enter the tubes g; 'but'simultaneously with the registering of the said perforation-s the valves 7L are opened, so thatthe charges'previously caught by said valves are permitted to fall to the ground, when the valves immediately close, so as to catch the descending charges. The seed thus released by the valves'h falls in a mass -in the trench made by the shoes L and isplanted by the rollers M. The cams c, immediately after acting on 'the projections d,,come in contact .with the levers lf, causing said levers to givea longitudinal thrust to the bar Lwhich causes the pawlsj to act upon the teeth of the ratchet-wheel's H, moving them thedistanoe round of one to'oth, and thereby permitting the de- -posit of lime at every eighth revolution ofthe cams. The deposit of this' lime is an important feature, for by observing it the driver is enabled to regulate the whole'machine, asvit is, evident that'ii' the lime deposits are in lines l equdistant fromand parallel with each otherl the hills planted must also be in even and straight lines, which fact greatly facilitates the subsequent plowing and cultivation of' the vcorn-plants. v

Having thus fully described my invention, ywhat I claim as new, and vdesire to secure by Letters Patent, "is-#- 1. The main shaft D, voperated by gearing' b b', connected with the driving-wheels B B, and the brakes P for regulating the motion of sai-d driving-wheels, so that the same 'shall' rotate alike and be under the control of the operator, as and for the purposes setforth.

2. The limeboxesG, mounted on the frame A, and provided with ratchet-wheels H, said vratchet-wheels being operated by Ameans .of pawlsj on each end of a slidebar, I, said slide-bar receiving its motionfrom the.. main shafty D by means ofthe cams c, actingon the -lever k, all arranged 4 and operating substantially as herein shown and described.
